Bronze Casting
Jo Davidson is known for sculpting in bronze. Bronze sculptures can be created through multiple processes, including lost-wax casting, sand casting, and centrifugal casting. Due to the small size of Ida Rubenstein, she was probably created using the lost-wax method, in which a clay model of the sculpture would first be created. Then a mould of the clay would be made in plaster, which allows for more detail to be added to the piece. Next a wax is cast from the mould, creating a hallow shape to be filled with molten bronze. Once the bronze is poured in and has cooled, the mould is chipped away until only bronze remains. As the pictures above show, bronze rods are left from where the melted bronze was poured; these rods are sawed off and the exterior is polished.
